The White House appears to be using cost overruns in the Fed's $2.5 billion project to build a case for dismissing Powell.

U.S. President Donald Trump might seek to fire Federal Reserve Chair Jerome Powell over alleged $700 million cost overruns on Fed's headquarters renovation. Trump's administration demands answers while Powell defends the project's necessity for safety and consolidation.

WASHINGTON, July 13 (Reuters) - U.S. President Donald Trump has the authority to fire Federal Reserve Chair Jerome Powell for cause if evidence supports that, White House economic adviser Kevin Hassett said on Sunday, adding that the Fed "has a lot to answer for" on renovation cost overruns at its Washington headquarters.
